Generally, a download manager enables downloading of large files or multiples files in one session.Many web browsers, such as Internet Explorer 9, include a download manager.Stand-alone download managers also are available, including the Microsoft Download Manager.

if you do not have a download manager installed, and still want to download the file(s) you've chosen, please note:

You may not be able to download multiple files at the same time.In this case, you will have to download the files individually.(You would have the opportunity to download individual files on the "Thank you for downloading" page after completing your download.)

Files larger than 1 GB may take much longer to download and might not download correctly.

You might not be able to pause the active downloads or resume downloads that have failed.

The Microsoft Download Manager solves these potential problems.It gives you the ability to download multiple files at one time and download large files quickly and reliably.It also allows you to suspend active downloads and resume downloads that have failed.

The Microsoft Online Services Sign-In Assistant provides end user sign-in capabilities to Microsoft Online Services, such as Office 365. The MOS SIA installs client components that allow common applications, such as Microsoft Outlook and Lync, to authenticate to Microsoft Online Services. The MOS SIA can also provide an improved sign-in experience, such that end users can access Microsoft Online Services without having to re-enter their credentials (such as a user name or password). This download is intended for IT Professionals, for distribution to managed client systems as part of an Office 365 client deployment, via System Center Configuration Manager (SCCM) or similar software distribution systems. For users who are installing Office 365 by means of the Office 365 Desktop Setup application, this download is not necessary, because the MOS SIA is installed as part of the Desktop Setup process.
